A hiring manager cannot tell a hard-working applicant from a lazy one by the adjective, because both of them write it. Reliable, productive and persistent each name a specific kind of effort, which makes them better picks, but the real replacement is a number that implies the effort: the caseload, the extra shifts, the years without a missed deadline. Choose the adjective that matches what you mean, and put the proof right next to it.

Leave these in the thesaurus
"Industrious" and "Assiduous" sound dated, and "Tireless" is the same unprovable claim said louder.
The one thing to remember
Check your last performance review for how your manager described your effort; their wording is usually more specific than "hard-working", and the example they gave is your bullet.
